The flashgun’s larger angle of coverage provides a higher safety margin for
perfect lighting of the subject. In normal operation, the Ex-Zoom mode produces
a softer illumination of the subject because more light is reflected back from the
walls and ceiling.
Setting procedure for the Ex-Zoom mode:
• Switch off the flashgun with the main switch
ቢ for approx. 5 seconds.
• Hold down the zoom button
ቭ on the flashgun.
• Switch on the flashgun with the main switch
ቢ.
• Release the zoom button
ቭ.
• Procede in the same sequence to switch off the ex-zoom mode.

The zoom reflector (main reflector)
The camera can automatically adjust the zoom reflector
ᕡ to the focal length of
the lens; alternatively, this can also be done manually with the Zoom button
ቭ
and the „+“ or „-“ buttons
ቪ.
Zoom 20: Illumination with wide angle diffuser (for 35 mm, from 20 mm focal length onwards)
Zoom 24:Wide-angle illumination (for 35 mm, from 24 mm focal length onwards)
Zoom 28:Wide-angle illumination (for 35 mm, from 28 mm focal length onwards)
Zoom 35:Wide-angle illumination (for 35 mm, from 35 mm focal length onwards)
Zoom 50:Standard illumination (for 35 mm, from 50 mm focal length onwards)
Zoom 70:Telephoto illumination (for 35 mm, from 70 mm focal length onwards)
Zoom 85:Telephoto illumination (for 35 mm, from 85 mm focal length onwards)
Zoom 105:Telephoto illumination (for 35 mm, from 105 mm focal length onwards)
For manual zoom control press the Zoom button
ቭ and adjust the desired zoom
setting with the „+“ or „-“ button
ቪ.
In the event that your camera with SCA adapter automatically transfers the zoom
setting of the lens, simply press the Zoom button
ቭ twice to reactivate automatic
zoom control after a manual zoom reflector adjustment.
Ex-Zoom mode (extended zoom)
The Ex-Zoom mode can only be used with system cameras that are capable of
exchanging data via the SCA 3000 adapter.
This mode was created for professional use during reporting work in dense
crowds. In the extended zoom mode, the flashgun’s zoom reflector position is
automatically adjusted one increment further towards a wider angle in relation to
the focal length of the camera lens, to guarantee wider coverage.
Example: Focal length of camera lens 50 mm; zoom reflector setting 35 mm
